Thank you very much Robert. Very simple and clear example of dealing with one-to-many relationships. This must be an elephant tutorial. Although cascading deletes are indeed a nice feature of sql servers, I'm fedup with sql inflexibility dealing with complex hierarchies of objects. I want to try OODB. Elephant is the only choice in a lisp land. Allegrocache is expensive, rucksack in its infancy. So far I like it.
